Katie Holmes and Jamie Foxx's big announcement

Katie Holmes and Jamie Foxx have announced their love to the world with an unusually public - and very romantic - trip to Paris... right in the face of her ex, Tom Cruise!

America’s Us Weekly magazine reports the undercover couple - strongly believed to have dated on the down low for almost three years - will be taking another romantic trip to Europe this northern summer.

It follows news of the pair’s recent rendezvous in Paris, where they reportedly enjoyed a sizzling four-day love in at the city’s five-star Park Hyatt Vendome Hotel - even though her ex husband Tom Cruise was filming a movie in the same city!

In a four-page report, the publication provided details of Katie and Jamie’s low-key tryst, reporting the 38-year-old jetted to the City of Light on May 7 via private jet.

Paparazzi-style photos of the pair departing on the same plane on May 11 were splashed across the front cover, beneath the headline, ‘Secret Paris Getaway!'

Foxx, 49, has been filming his ‘Robin Hood’ remake in France ahead of its release next year.

“She’s head over heels with him,” a source is quoted as saying, before adding: “They’re talking about planning a summer trip together in Europe.”

Another friend said, “They’re very serious” - with insiders pointing to their increasingly public antics.
